2.30.1. Work of pushers
THE GENERAL DATA

Oil is brought to a pusher through a lateral aperture in the case of a pusher which is connected to a flute and an aperture in плунжере. Then oil passes through dosing out valve of a pusher and on the channel of a bar of a pusher moves to the valve lever. During moving of a pusher under the influence of a camshaft cam the return ball valve sits down on a saddle and locks oil in a cavity under плунжером. Thus the case of a pusher and плунжер движутся as a single whole. A sleeve плунжера, moving a pusher bar, opens the valve. Under the influence of resistance клапанной springs there is a small leak of oil from a cavity плунжера through radial backlashes. Because of it плунжер receives also small moving concerning the pusher case. In a closing-time of the valve the pusher lowers ся. When the valve sits down on a saddle, the spring плунжера quickly returns it in a starting position. Thus the return ball valve opens and passes oil in a cavity плунжера. Thus, backlashes in a valve drive are eliminated.
